Linac4 Low Energy Beam Measurements with Negative Hydrogen
/ Scrivens, R (CERN) ; Bellodi, G (CERN) ; Crettiez, O (CERN) ; Dimov, V (CERN) ; Gerard, D (CERN) ; Granemann Souza, E (CERN) ; Guida, R (CERN) ; Hansen, J (CERN) ; Lallement, J B (CERN) ; Lettry, J (CERN) et al.
Linac4, a 160 MeV normal-conducting H- linear accelerator, is the first step in the upgrade of the beam intensity available from the LHC proton injectors at CERN. The Linac4 Low Energy Beam Transport (LEBT) line from the pulsed 2 MHz RF driven ion source, to the 352 MHz RFQ has been built and installed at a test stand, and has been used to transport and match to the RFQ a pulsed 14 mA H- beam at 45 keV.

Status and plans for Linac4 installation and commissioning

Linac4 is a normal conducting 160 MeV Hˉ linear accelerator presently being installed and progressively commissioned at CERN. It will replace the ageing 50 MeV Linac2 as injector of the PS Booster (PSB), increasing at the same time its brightness by a factor of two thanks to the higher injection energy. [...]

LINAC4 low energy beam measurements
/ Hein, L M (CERN) ; Bellodi, G (CERN) ; Lallement, J B (CERN) ; Lombardi, A M (CERN) ; Midttun, O (CERN) ; Posocco, P (CERN) ; Scrivens, R (CERN)
Linac4 is a 160 MeV normal-conducting linear accelerator for negative Hydrogen ions (H−), which will replace the 50 MeV proton Linac (Linac2) as linear injector for the CERN accelerators. The low energy part, comprising a 45 keV Low Energy Beam Transport system (LEBT), a 3 MeV Radiofrequency Quadrupole (RFQ) and a Medium Energy Beam Transport (MEBT) is being assembled in a dedicated test stand for pre-commissioning with a proton beam.

Space Charge Compensation in the Linac4 Low Energy Beam Transport Line with Negative Hydrogen Ions
/ Valerio-Lizarraga, C (CERN ; Sonora U.) ; Lallement, J B (CERN) ; Leon-Monzon, I (Sinaloa U.) ; Lettry, J (CERN) ; Midttun, O (CERN ; U. Oslo (main)) ; Scrivens, R (CERN)
The space charge effect of low energy, unbunched ion beams can be compensated by the trapping of ions or electrons into the beam potential. This has been studied for the 45 keV negative hydrogen ion beam in the CERN Linac4 Low Energy Beam Tranport (LEBT) using the package IBSimu1, which allows the space charge calculation of the particle trajectories.

Beam Dynamics and RF Design Studies for the New RFQ for CERN Linac4 Upgrade
/ Pommerenke, Hermann (CERN) ; Bellodi, Giulia (CERN) ; Grudiev, Alexej (CERN) ; Kumar, Sarvesh (CERN) ; Lombardi, Alessandra (CERN)
The 352 MHz Linac4-RFQ is the first rf accelerating structure of the CERN accelerator complex, accelerating an H-beam to 3 MeV. After successful commissioning in 2013, superficial vane damage has been observed in 2020. [...]
